I am using a STM32L031K in the development board.
Everytime that you connect the board to the PC after some seconds the mass storage pops up with the name 'NODE_L031K6'.
I have programmed the microcontroller to print all the time a letter 'A' by means of the virtual serial port.
As soon I connect the board I see how the letter is print in my serial terminal but when the Mass storage pop up the communication stops!!
Any idea how to solve this? Is it a drivers problem?
Yesterday I thought that I fix the problem uninstalling the driver and installing again, it worked for a while since I turned on the PC again and... unfortunatelly the same history.
